Answer 1

Answer:

x = 126

Step-by-step explanation:

-$\frac{2}{7}$x - $\frac{8}{21}$x + $\frac{1}{3}$x = -42

-$\frac{2}{7}$x (multiply numerator and denominator by 3)

-$\frac{6}{21}$x

$\frac{1}{3}$x (multiply numerator and denominator by 7)

$\frac{7}{21}$x

-$\frac{6}{21}$x - $\frac{8}{21}$x + $\frac{7}{21}$x = -42

-$\frac{7}{21}$x = -42 (multiply everything by -21)

7x = 882 (divide everything by 7)

x = 126
